Unfortunately, we have not
received payment or heard from you regarding your unpaid account balance of
$[AMOUNT], which was due on [DATE, ex, March 11, 2016]. As three months have past since the due date,
we will be forced to take legal actions if we do not receive payment within the
next five business days.

[NAME, ex. Mr. Smith], we
sincerely hope that we may resolve this issue and avoid taking legal actions
which may ultimately cost both of us an amount in frustration and time far
greater than that which is involved here.
